Schneider Electric A9D10810 iC60H RCBO 10 A 10 mA 1P+N

A9D10810: Acti9 iC60H RCBO 10 A C curve 10 mA

The A9D10810 is a Schneider Electric Acti9 iC60H residual current breaker with overcurrent protection, an RCBO, in a single module that protects one phase conductor plus neutral. The datasheet lists a rated current of 10 A, a C curve, 10 mA earth-leakage sensitivity and a 230/240 V AC supply. Seven Star LLC supplies the A9D10810 in Oman and the GCC as an independent supplier in Muscat, mainly to panel builders and maintenance teams that need a like-for-like circuit protection device.

On the datasheet generated on 8 Nov 2026 the A9D10810 is not marked as discontinued. Confirm stock before the design relies on it.

Fitting the A9D10810 in a board and climate limits

The unit is clip-on to a DIN rail and occupies 2 pitches of 9 mm, which is 18 mm. It measures 110 mm high and 77.5 mm deep and weighs 205 g. The top screw clamp terminal accepts 1 to 25 mm² rigid or 1 to 16 mm² flexible, and the bottom 1 to 16 mm² rigid or 1 to 10 mm² flexible. The stripping length is 14 mm at the top and 13 mm at the bottom, with tightening torques of 3.5 N.m and 2 N.m. The datasheet states that comb busbar and distribution block compatibility is not provided, so wire it individually.

Test the earth-leakage function with the test button after installing A9D10810, and record the date. Neutral position is on the left, so watch the wiring orientation.

The datasheet lists IP20 for the device and IP40 in a modular enclosure, tropicalisation class 2, relative humidity of 95 % at 55 °C, an operating range of -15 to 60 °C and storage from -40 to 85 °C. The 60 °C upper limit is wider than for many residual current devices and helps in warm Gulf switchrooms, but the rated current is referenced to 50 °C, so a board running hotter should be checked carefully for the A9D10810.

Short-circuit data for the A9D10810

The breaking capacity is stated as 10,000 A Icn at 230/240 V AC 50/60 Hz and the service breaking capacity Ics as 7,500 A, with energy limitation class 3. Rated insulation voltage is 400 V AC and impulse withstand is 4 kV. The device is suitable for isolation, shows its contact position and has ON/OFF indication on the front, and it is padlockable with a 4 mm padlock for lock-out during maintenance.

Surge current withstand is listed at 250 A for an 8/20 µs impulse, which is relevant where lightning-induced surges are possible. Mechanical durability is 20,000 cycles and electrical durability is 5,000 cycles.

Where such devices are used in Oman and the GCC

Single module RCBOs like this unit are used in distribution boards for offices, workshops, camps, pump houses and utility rooms, and in small control panels on industrial sites. Protecting each circuit separately limits the outage when an earth fault happens, which is helpful where dust, humidity and heat raise leakage on outdoor circuits.

What the 10 A rating means for the A9D10810

The 10 mA sensitivity is unusually low. It is chosen for circuits where a very small leakage current must be detected, and it needs a quiet circuit because small amounts of normal leakage from filters or long cables can reach the threshold. Confirm with the project specification that 10 mA is truly required before choosing it over the 30 mA versions.

The rated current is stated at 50 °C, which is a practical point for Gulf boards because it is the reference temperature for the thermal trip. The C curve is the common characteristic for mixed loads with moderate inrush, and the thermal-magnetic trip unit means overload and short-circuit are both handled by the device, while the earth-leakage part adds the residual current function.

The A9D10810 within the A9D iC60H group

Seven related devices share the C curve, the 18 mm width and the 10 kA breaking capacity, and they differ in current and sensitivity.

Technical data of the A9D10810

How a combined RCBO differs from an MCB plus RCCB

An RCBO contains the overcurrent protection and the earth-leakage detection in one 18 mm wide module, so the A9D10810 protects its own circuit individually. A fault on one circuit therefore trips only that device, which is a clear advantage over an RCCB that supplies a group of circuits and drops them all together. The datasheet lists type A earth-leakage protection with instantaneous action, with voltage-dependent residual current tripping, which means that the earth-leakage function relies on the supply voltage to trip.

That detail matters for one reason: in a voltage-dependent device, loss of the neutral or a very low supply voltage may leave the earth-leakage function ineffective, so check how the project handles that case in its protection design.
